The sweeping attacks by Israel, which began early Friday, have killed more than 70 people, including four of Iran’s top security chiefs, and damaged Iran’s main nuclear site at Natanz. Iran retaliated by launching scores of missiles at Israel. At least three people have been killed and dozens more wounded during these attacks.

Iran responded with an aerial attack involving about 100 drones, Israel said, but all of them were shot down before hitting their target. The U.S. did not provide any assistance or have any involvement in the Israeli strike, a U.S. official told ABC News.
